Levonorgestrel - Does weight contribute to it being ineffective?

My girlfriend took it last night, she took it 5 hours after the 72 hour deadline, and she is around 200lb. She has diarreah, nausea, vomiting and occasional stomache cramps now, does that mean its working? Or is it likely it failed

If she has been vomiting/had diarrhea within an hour or 2 of taking the pill, I think it probably did not work too well... I personally have never had adverse symptoms from that pill, but a reaction like hers sounds severe and probably not related to the pill so much as perhaps food poisoning or the flu.
